About
This phase I trial studies the side effects and best dose of Chinese herbal formulation PHY906 when given together with sorafenib tosylate in treating patients with advanced liver cancer. Biological therapies, such as Chinese herbal formulation PHY906, may interfere with the growth of tumor cells and slow the growth of tumors. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Sorafenib tosylate may also stop the growth of liver cancer by blocking blood flow to the tumor. Giving Chinese herbal formulation PHY906 together with sorafenib tosylate may work better in treating advanced liver cancer.
Full description
PRIMARY OBJECTIVES:
I. To characterize the safety and tolerability of KD018 (Chinese herbal formulation PHY906) in combination with daily sorafenib (sorafenib tosylate) and to determine the maximum tolerated dose (MTD) of the combination of KD018 plus sorafenib to bring forward into phase 2.
SECONDARY OBJECTIVES:
I. To describe the efficacy of the combination of KD018 plus sorafenib at the explored dose-levels in terms of best overall response as defined by Response Evaluation Criteria in Solid Tumors (RECIST) guidelines.
II. To assess the safety and tolerability of the combination of KD018 plus sorafenib as measured by the rate and severity of adverse events (AEs).
III. To determine the steady state of sorafenib after KD018 exposure at pre-dose and 1 hour and 2 hours post-dose at the explored combination dose-levels using concentrations at pre-dose (Cmin) and at 1 hour (C1h) and 2 hours (C2h) post-dose.
TERTIARY OBJECTIVES:
I. To assess the effect of treatment on soluble markers of angiogenesis, fibroblast growth factor (FGF), vascular endothelial growth factor (VEGF), placental growth factor (PLGF), soluble vascular endothelial growth factor receptor 1 (sVEGFR1), sVEGFR2, apoptosis (i.e. M30 monoclonal antibody [M30] and M65) and on the insulin-like growth factor (IGF) axis including molecules such as IGF-binding protein 2 (IGFII).
II. To correlate the above soluble biomarker measurements with clinical endpoints.
III. To examine the correlation between the soluble biomarkers.
IV. To examine the predictive relationship of immunohistochemical tumor biomarkers at baseline, i.e. phosphorylated ribosomal protein S6 kinase (pS6), p-protein kinase B (pAKT), p-mitogen-activated protein kinase 1 (ERK), p-mitogen-activated protein kinase kinase (pMEK), hypoxia-inducible factor 2, alpha subunit (HIF2a), phosphatase and tensin homolog gene (PTEN), signal transducer and activator of transcription 3 (acute-phase response factor) (STAT3) and tumor protein p53 (p53), as well as of mutational status, i.e. p53, phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (PIK3CA) and PTEN, with efficacy endpoints (time to progression [TTP]).
V. To determine if soluble apoptosis markers (M30/M65) correlate with proliferative markers at baseline (proliferation-related Ki-67 antigen [Ki67] and p53) in archival tumor samples.
VI. To examine the relationship of immunohistochemical and/or soluble biomarkers with subgroup classification namely, patients with hepatitis B virus (HBV), patients with hepatitis C virus (HCV) and patients with other etiologies.
VII. To explore potential biomarker differences within patient subgroups, namely, patients with HBV, patients with HCV and patients with other etiologies.
VIII. To determine the effect of KD018 on cytokine/chemokine levels including interleukin (IL)-2, IL-4, IL-5, IL-6, IL-10, monocyte chemotactic protein 1 (MCP-1), tumor necrosis factor (TNF)-alpha, interferon (IFN)-alpha, VEGF, FGF-basic (b), sargramostim (GM-CSF), filgrastim (G-CSF).
IX. To explore potential relationships between efficacy and Cmin of sorafenib after co-administration with KD018 and between occurrence of adverse events and C1h/C2h endpoints (efficacy, safety, pharmacokinetics [PK]).
OUTLINE: This is a phase I, dose-escalation study of Chinese herbal formulation PHY906.
Patients receive Chinese herbal formulation PHY906 orally (PO) twice daily (BID) on days 1-4, 8-11, 15-18, 21-24 and sorafenib tosylate PO BID on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months.
